It good kit. I have a V2.2 its the older and bigger ecu. Look on the MS site www.msefi.com Its not a simple fit kit, but with a bit of reading and testing it works ok. One downside is the lack on base maps. But if fitted with a wideband or narrowband (limited) the system can self learn a rough base map.
Going to be fitting One on my BOB power sierra soon.
